This declaration is based on the BRE Environmental Profiles 2013 Product Category Rules for Type III environmental product declaration of construction products to EN 15804:2012+A1:2013. Comparability Environmental declarations from different programmes may not be comparable if not compliant with EN 15804:2012+A1:2013. Comparability is further dependent on the product category rules used and the source of the data, e.g. the database. See EN 15804:2012+A1:2013 for further guidance. Construction Product Product Description Sikalastic -625 is a single component, cold applied, moisture triggered polyurethane membrane. It cures to form a seamless, durable and weather resistant waterproofing solution for the exposed roof areas. The results in this EPD refer to the standard system, consisting of an embeddment layer of 1 L/m2 and Sika Reemat Premium reinforcement, and a top coat of 1 L/m2.

This process is followed by the manufacture of a pre-polymer and hardener by Incorez Ltd under the control of Sika Liquid Plastics, in accordance with formal quality plans. The specified ingredients are blended and reacted together in stainless steel cylindrical mixing vessels in accordance with pre-set parameters which include temperature, mixing, time, vacuum pressure, and this is done under a nitrogen blanket to eliminate moisture. Every batch is QC tested both in process and on completion in accordance with formal quality plans. Once completed the batches are gravity fed via a filtering system into filling hoppers and tinned off as specific with nitrogen purging to each container.

5 The process flow diagram is shown below: Construction Installation The Sikalastic -625 is a single pack polyurethane coating that is cold applied on site; it cures to provide completely seamless waterproofing protection with an aesthetically pleasing finish. The product is available in a range of colours. The membrane is fully reinforced with a glass fibre mat, which is easily moulded around detail areas allowing speed of application on complex roofs. Use Information Installation works must be carried out by a competent contractor, in accordance with Sika Limited. During the service life of the membrane system there is no ordinary maintenance, repair/refurbishment or replacement required, if it is correctly and properly applied. Therefore no scenario for the use phase and maintenance is defined. Reference Service Life The reference to service life of Sikalastic -625 membrane is as stated by the ETA Certificate 13/0788. Available evidence indicates that the system will have an expected service life of 25 years. See ETA for details. BF1331ECOP Rev 0.3 Page 5 of 10 BRE Global Ltd 2016

6 End of Life When the Sikalastic -625 reaches the end of its life, the system may be primed and further material applied. At the end of its service life the building is demolished, and as the Sikalastic membrane systems are attached to the substrate it is generally taken to landfill. The demolition process concerns mainly the structure of which the membrane system is a minor part. Therefore, for this stage no other steps are considered necessary except for the transportation to landfill and landfilling. Life Cycle Assessment Calculation Rules Declared / Functional unit 1 m2 installed system for a reference service life of 25 years. System boundary In accordance with the modular approach as defined in EN 15804, this cradle to gate with options EPD includes the product stage (A1-A3), construction process stage (A4-A5), and end-of-life stage (C1-C4). Data sources, quality and allocation The primary data provided by Sika derive from the plant at Preston, UK for 2014, with total site mass-weighted allocation to product, as the process is similar for all membranes produced there. Background LCI datasets are taken from the databases of GaBi software and ecoinvent Version 3.1. All datasets are less than 10 years old. Benefits from incineration and landfilling of product losses and for the disposal of packaging are credited in Module D; this also applies to the reuse of wooden pallets. Cut-off criteria All data was taken into consideration (recipe constituents, thermal energy used, electricity used). Transportation was considered for all inputs and outputs. The manufacturing of the production machines and systems and associated infrastructure were not taken into account in the LCA. BF1331ECOP Rev 0.3 Page 6 of 10 BRE Global Ltd 2016

The partial reuse of pallets from packaging is also included in Module D as avoided production of new pallets. Interpretation The following chart shows the relative contributions of the different modules to the various environmental impact categories and to primary energy use in a dominance analysis. It is clear that most impacts come from Module A1-3, though the installation of the system (A5) also contributes, due to the impacts from the membrane's application (the VOC emissions are visible for POCP - Photochemical Ozone Creation Potential), from the production of the reinforcement (especially for ADPE - Abiotic Depletion Potential Elements) and due to the disposal of waste to landfill (contributing to GWP -Global Warming Potential). For this reason, the Product Stage is examined more closely in the following interpretation. Energy resource use Pre-product manufacturing (73%), packaging (20%) and the manufacturing process (6%) account for the total of the use of renewable primary energy resources (PERT). The manufacturing of raw materials (94%) has the greatest impact on the use of non-renewable primary energy resources (PENRT), while the impact of the production process (due to electricity and nitrogen consumption) measures 4%. Environmental impacts The dominant influence in all impact categories for Module A1-A3 comes from pre-product manufacturing, with at least 93% in each case, except for Eutrophication Potential (EP), where the production process contributes the most (69%), from nitrogen released during processing. Within pre-product manufacturing, polymers play an important role regarding GWP, EP, Photochemical Ozone Creation Potential (POCP), ADPE and Abiotic Depletion Potential - Fossil Fuels (ADPF). The pigments/fillers contribute mostly to Acidification Potential for Soil and Water (AP) and Ozone Depletion Potential (ODP). The solvents also make a contribution to ODP and POCP. The additives and thickeners' contribution is not so significant. The raw materials with the greatest effect on the impacts also show the greatest percentage by mass of the system: polymers and pigments/fillers. The manufacturing process (mainly the energy inputs, nitrogen input and release) contributes mostly to EP (69%) and GWP (5%). BF1331ECOP Rev 0.3 Page 9 of 10 BRE Global Ltd 2016
